With no lead officially cast in Martin (Casino Royale) Campbell’s take on the DC Comics superhero Green Lantern, Warner Bros. has decided to push the Emerald Knight’s big screen debut back six months to June 17, 2011 from its original scheduled date of December 17, 2010. No word whether this will affect the plans to start shooting in Australia in September or whether the move is to give Campbell more time for post-production and special FX.

Casting for the lead has included Chris Pine from the upcoming STAR TREK movie and BRIAN AUSTIN GREEN (TERMINATOR: THE SARAH CONNOR CHRONICLES, BEVERY HILLS: 90210) but nothing is confirmed yet.

Preproduction on Green Lantern is set to begin in July, and filming scheduled to start in November. Warner hopes to release the film in December 2010.

Martin Campbell, director of “Casino Royale,” will be at the helm of the comic book’s big screen adaptation, working from a script by Greg Berlanti and Michael Green. Donald Deline will produce with a reported budget of $150 million.

My take on the review: Bizarro sounds a little bit like the Hulk. Ridiculously powerful, misunderstood, and a margially controllable wild card. General Zod and Ursa also are back (from Superman 2) and heavily involved. It sounds like an interesting concept for a graphic novel idea but I seriously doubt that this is the way they will go with retooling the Superman movie franchise.

Warner Bros. made the announcement Friday afternoon, saying that the combined domestic and international gross had totaled $1,001,082,160 to date — about $533 million domestically and $567 million overseas.

Only “Titanic,” with $1.8 billion, “The Lord of the Rings: The Return of the King” and “Pirates of the Caribbean: Dead Man’s Chest” have topped the billion-dollar worldwide mark previously.
